Abstract

Abiotic stress is considered a major factor limiting crop yield and quality. The development of effective strategies that mitigate abiotic stress is essential for sustainable agriculture and food security, especially with continuing global population growth. Recent studies have demonstrated that exogenous treatment of plants with chemical compounds can enhance abiotic stress tolerance by inducing molecular and physiological defense mechanisms, a process known as chemical priming. Chemical priming is believed to represent a promising strategy for mitigating abiotic stress in crop plants. Plants biosynthesize various compounds, such as phytohormones and other metabolites, to adapt to adverse environments. Research on artificially synthesized compounds has also resulted in the identification of novel compounds that improve abiotic stress tolerance. In this review, we summarize current knowledge of both naturally synthesized and artificial priming agents that have been shown to increase the abiotic stress tolerance of plants.

化学启动增强植物非生物胁迫耐受性的研究进展

摘要

非生物胁迫被认为是限制作物产量和品质的主要因素。制定缓解非生物胁迫的有效策略对于可持续农业和粮食安全至关重要，特别是在全球人口持续增长的情况下。最近的研究表明，用化合物对植物进行外源处理可以通过诱导分子和生理防御机制来增强非生物胁迫耐受性，这一过程称为化学启动。据信化学引发是缓解作物非生物胁迫的一种有前途的策略。植物生物合成各种化合物，例如植物激素和其他代谢物，以适应不利的环境。人工合成化合物的研究也导致鉴定出改善非生物胁迫耐受性的新型化合物。
